As per title really could do with a decent budget CCTV kit that has decent night vision and a clear view during the day to mainly to watch my drive and cars and approach to the house generally. How do these things work regarding recording? I take it you have to have sone kind of large data storage device? Also don't fancy having a load of cables trailing all over, does anyone know of a wireless kit? (if even exist) Any thoughts or recommendations appreciated! Thanks.
